Post Hovercraft Lab

a. I'm not entirely sure what riding on the hover craft because I never got a chance to participate. But, I believe those who did ride it felt as though they we gliding and would never stop. The hover craft is different from riding on any other vehicle because of the lack of surface friction, you feel like you would go on forever.

b. I learned that inertia has a lot to do with the mass of something. The greater the mass the more the harder the initial force for the object to start is harder to create, and the same with slowing down. I also learned that while gliding on the hovercraft, equilibrium is reached when the craft reaches constant velocity.

c. Acceleration depends on the initial push of the object for it to start moving. The harder the initial opposite force acting on it the higher acceleration the craft is going to have.

d. Based on this lab, I would expect to have constant velocity when the craft fished accelerating and reached the speed it would remain at.

e. Some members during this lab were harder to stop because some had more mass than others. As I explained earlier mass and inertia coincide with one another. With more mass, that means the object is harder to accelerate both negatively and positively.

  1. I like that each of your paragraphs started off as "a", "b", "c"... It made your answers really clear and precise. Something I did not mention, but you did, was that it felt like the "gliding... would never stop". I agree with you on your answer for "e", where you mentioned how mass and inertia are directly related. Some thing I would change is that there are a few grammatical errors in this post (which can be edited easily). One of them is in answer "d" where you may have meant to say "finished" but instead said "fished". I like that you didn't ramble to get your point across though. All of your answers are direct and well-defined.
